High hardness piston rod

Normalizing: It refers to the heat treatment process that steel parts are heated 30-50℃ over the critical temperature, and after certain time of heat preservation, the steel parts are cooled under immobile air condition.

LM shaft is manufactured by the advanced process of fine cold drawing, fine grinding and high precision polishing, conforming to or above relevant national standards and specifications for various technical indices.
